However, the question is: should I expect for a 22.0.X .elc file to work on 21.4? I would've assumed "not", but for this comment on `define-derived-mode':
If it is easy to make this work (or work more), we can do it, but I'd rather not do a lot of work for that sake. I think that such compatibility is much less important than it once was. It isn't hard to maintain two sets of .elc files if you have two Emacs versions installed. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
